I, too, am laughing my head off reading all these comments. I learned Don Gato from Mr. Henley in fifth grade in Cincinnati, Ohio (1973) I don't remember much from fifth grade but for some reason was able to sing almost the entire song to my kids using their stuffed kitties as props. I just couldn't remember the verse after "And they held a consultation about how to save their patient," so like Suzette I have made up my own ending to the song for years. Tonight I thought I would go on line for kicks and see if I could find the lyrics and there they were! I wonder what makes this song so memorable to so many people?
